Crossloading
Transferring memories, pages and presets directly from one
controller to another. Also refers to transferring firmware
from one Studio Color fixture to other fixtures on the same
DMX link. See Chapter 7 for more information about
crossloading between controllers. See the Studio Color User
Manual for information about crossloading firmware
between fixtures.
Delay Time
The value of the Delay parameter, which determines how
long one page in a loop “plays” before moving on to the next
page in the loop. For example, selecting 2.0 seconds for the
Delay construct equates to a delay time of 2.0 seconds. The
delay time is affected by the
<Rate>
knob as described in the
section titled “Setting Rate and Delay Time” on page 4-18.
Dichroic filters
A dichroic (from Greek, meaning “two-color”) filter achieves
a richly-saturated color without using any pigmented
(colored) materials. In simple terms, it achieves this effect by
either reflecting or “cancelling out” through destructive
interference all but a narrow range of the light spectrum.
The “dichroic” name refers to the fact that one color (or set of
colors) is reflected or cancelled out, and one color is allowed
to be transmitted through the dichroic filter.
The dichroics used in Studio Color are all manufactured at
the High End Systems Optical Coating and Assembly
Laboratory in Austin, Texas. They are made from a base of
Pyrex
®
-like glass material coated with multiple, microscopic
layers of specialized materials separated by junctions that
either transmit or reflect certain wavelengths of light,
accounting for the resulting color.
Dichroic filters offer a number of advantages over traditional
gel filters: since they are made of Pyrex-like glass and absorb
almost no heat themselves, they theoretically have no failure
mechanism; they transmit more light than gels; and their
